Trigger event for inputs

There are some special events that are avaialble as the method's element. You can call them directly such as following:
// For text box and textarea

// For form element

// For any element

Trigger a native event

const trigger = function (ele, eventName) {
const e = document.createEvent('HTMLEvents');
e.initEvent(eventName, true, false);
You can trigger the `change`, `keyup`, `mousedown` and more by calling
trigger(ele, 'mousedown');

Trigger a custom event

The sample code below triggers a custom event named `hello` with a data of `{ message: 'Hello World' }`:
const e = document.createEvent('CustomEvent');
e.initCustomEvent('hello', true, true, { message: 'Hello World' });

// Trigger the event
